I've added several new blogs to Planet Lisp. Vsevolod Dyomkin, Pixel, Jorge Tavares, and Quicklisp news.
I hesitated to add the Quicklisp blog, because I really prefer blogs written from a personal perspective and not product announcement blogs. I hope you find the addition more informative than irritating.
I also removed several blogs that have not been updated with Lisp-tagged content in more than a year: François-René Rideau, Peter Seibel, Dmitry Kalyanov, Kevin Reid, and Simon Leinen. (If Peter blogs about the toot project
I'll have to add him back in...)
